I guess sometimes humor can be interesting!
The JBL Studio 530 is a bookshelf - however, it still plays below 50 hz.
I have owned them and do highly recommend them.
They are good for both music and HT - and they are not that hard to drive, plus
they can/will get Loud. The all around word on that speaker is positive.
Some speakers that others have preferred the Studio 530 over are >>
Aperion Intimus 5B, Ascend Acoustics Sierra, Audioengine P4, Axiom Audio M22,
B&W 683 & 685, Dali Mentor & Icon, Dynaudio Contour & Focus, Epos Epic 1,
GoldenEar Triton & Aon, Linn, NHT Classic 3, Magnepan MMG & 1.6,
Monitor Audio Silver RS6 & RX1, RSL CG4, Revel F12, and Tekton Design Model 4.5.
Your option and call - the choice is up to you - enjoy the adventure.
